After you have have factored the numerator, you found x-4 as factor.
So try dividing that into the denominator.
However it is easier to just apply l'hopital's rule immediately. Note top and bottom eval to zero at 4, so
limit will equal limit after replacing numerator and denominator by their derivatives.
Try it out.
luck
